2018 Chevrolet Silverado 2500 Service and Repair Manual

This factory service and repair manual for the 2018 Chevrolet Silverado 2500 returns to a single powerplant, the 5.3L overhead-valve V8 of 325 cubic inches, naturally aspirated and rated for flex-fuel or gasoline, fitted to extended, standard and crew cabs sold in LS trim. One engine and one trim narrow the branching considerably: what a technician chooses between is cab length and the equipment that comes with it, while the engine, transmission and axle specifications hold across the whole year.

Known issues on the 2018 Silverado 2500. Five recalls stand for 2018. One covers front seat belt retractors assembled with the wrong torsion bar, so they may not hold as designed in a crash. Two describe an engine block heater cable and its terminals shorting and raising a fire risk. Another involves a rear fuel tank that can collapse and stop fuel reaching the front tank, stalling the truck.
